BMPROVEAM ENT IN Ol L-EJECTORS.

Specification forming part of Letters Patent No. 47,227, dated April 11, i865.

To @ZZ whom, it may concern,.-

Beit known that I, S. F. SCHOONMAKER, of the city, county, and State of New York, have i-nvented a new and useful Improvement in Petroleum-Elevators; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The present invention relates to a new and useful improvement in apparatuses used for raising for petroleum from deep wells, but which are applicable to the raising of any liquids to great heights or from great depths; and it consists in delivering the air to the oil, which is to be forced up through the oil-pipe and out of the well by the force of its blast, through a series of small pipes having their delivery ends arranged around in a circle, and so that as the air issues from the various pipes it shall form an annular blast, the space around and between the said pipes being open and communication had for the oil to the interior" of the blast, the advantages of which have been particularly set forth inthe specication accompanying another application dated February 22, 1865, made by me for apatent on an improved petroleum-elevator. I" have also made another improvement in elevators for petroleum, which can be used in connection with the air-blast herein described, or with the blast described in the specification before referred to, and which will be presently described. .i

In the accompanying drawings my improvement is represented, Figure l being a central vertical section of the elevator;` Fig. 2, a crosssectiou in the plane of linew m, Fig. 1.

Similar letters of reference indicate like parts.

a is an airpipe extending from top of well nearly to its bottom, and, entering the oil-pipe c at or near its lower end, passes upward a short distance in the central axis of the same,

same horizontal plane and with their deliv ery-apertures in the form of a circle, or in any other described form. The space g g between the pipes f f, Ste., at their upper ends,is open,

and communicates by the spaces h h, Sac., bel tween the said pipes, with the oil-chamber of l the pipe b surrounding the air-pipe a.

Above the nozzle d of air-pipe, with its apex toward the same, is au inverted cone, Z, hung by its base to a vertical screw-rod, m, of a cross-bar, n, secured in oil-pipe b, said cone,` being susceptible of adjustment at pleasure.

To the interior periphery of the oil-pipe b, projecting therefrom toward the adjustable cone Z, and by its larger base a hollow trun-` cated conical diaphragm, o, is secured, tothe lower or smaller base of which is attacheda similar hollow truncated conical diaphragm, p, and with its smaller base extending only a short distance toward the interior surface of` the oil-pipe, but sufficiently to form a guard, as it were, to the air-blast, `and preventits be-` ingl diverted from its direct passage up and:

` through the opening q, between the said ad# the oil-pipe, in the usual manner, by its great` velocity, and which, in the present air-blast, is greatly increased, as the oil not only communicates with the exterior surface of the blast, but also with its interior, as herein described, whereby a greater proportion of oil is forced up through the pipe b than would be were the oil to communicateonly with the exterior surface of the blast, as has heretofore been the case, because a corresponding greater suction is produced. l

By the use of the double l hollow truncated cone or diaphragm, in connection with the ad-z l justable cone, arranged so as to have an open space between the two, a better guiding-pas-` sage for the oil is providedthan would be the 4 case were the space between the cone andthe l interior surface` of the pipe to be left entirely open, as is evident without further description, and, furthermore, the full capacity of the oiltube up to the orifice ofthe air-blast is allowed and given to the oil within the tube.

It is obvious that by the use of the double truncated and guiding diaphragm and the adjustable cone, the parts of the apparatus can be adjusted together Without reference to the size of the oil-tube below or above the airnozzle, thus allowing a large or small pipe to be used, as may be desired, the advantages of which are evident.

I do not claim the use of steam or compressed air for elevating oil or other liquids.

I claim as new and desire to secure by Letters Patent- 1. Forming the delivery-nozzle of an airblastnpipe in elevators for petroleum or other liquids of a series of pipes of any desired number and size, with their delivery ends in the same horizontal plane, and having the form S.
